CLAIM OF PRIORITY

BACKGROUND

1. Technical Field

This disclosure relates generally to the field of wireless mobile devices that can utilize two or more networks, and, more specifically, this disclosure pertains to the field of determining a network to utilized based on one or more speed determinations.

2. Description of the Related Art

In the past, a mobile device (e.g., a smart-phone, a tablet computing device, etc.) could utilize either a mobile telephone network or a wireless network provided via one or more Wi-Fi access points. Mobile telephone network operators have tried to offload data traffic (e.g., non-voice data) to a Wi-Fi network implemented via Wi-Fi access points. However, when the mobile device is traveling at or above a certain speed, offloading data traffic (e.g., non-voice data) to a stationary Wi-Fi access point can be ineffectual or unproductive, since a coverage area of the stationary Wi-Fi access point is usually too small to be used for an effective period of time while the mobile device is traveling at or above the certain speed.

DETAILED DESCRIPTION

In one or more aspects, a mobile device, operated by a user, can determine one or more parameters and can utilize a wireless network based on the one or more determined parameters. For example, the mobile device can determine its speed and can utilize a wireless network based on its determined speed. For instance, the mobile device can determine a speed above a threshold speed and utilize a mobile telephone network for data communications (e.g., packet data communications such as Internet protocol communications, etc.) rather than a wireless local area network. For example, the mobile device can be within a communications range of a wireless access point that implements a wireless local area network and can utilize a mobile telephone network for data communications rather than a wireless local area network when the mobile device is traveling at or above a certain speed. In one instance, when the mobile device is traveling at or above a certain speed, utilization of a wireless local area network may not be possible or may be possible for a period of time transpiring that may not be considered useful by the user of the mobile device. In another instance, when the mobile device is traveling at or above a certain speed, utilization of a wireless local area network may not be optimum for communications for a period of time transpiring that may not be considered useful by the user of the mobile device.

In one or more aspects, a mobile device operated by a user can determine its speed and can utilize a wireless network based on its determined speed and based on a signal received from a wireless local area network. In one example, the mobile device can receive a signal from a wireless access point that implements a wireless local area network, and based on the signal and the determined speed of the mobile device, the mobile device can utilize the wireless access point at or above a certain speed determined for the mobile device. For instance, the wireless access point can transmit a beacon that can indicate that the wireless access point can be utilized for data communications (e.g., packet data communications such as Internet protocol communications, etc.) when the mobile device is traveling at or above a certain speed. In another example, the mobile device can receive a signal from a wireless access point that implements a wireless local area network, and based on the signal and the determined speed of the mobile device, the mobile device can utilize the wireless access point at or below a certain speed determined for the mobile device. For instance, the wireless access point can transmit a beacon that can indicate that the wireless access point can be utilized for data communications (e.g., packet data communications such as Internet protocol communications, etc.) when the mobile device is traveling at or below a certain speed.

In one or more aspects, a mobile device operated by a user can determine its speed and can utilize a wireless network based on its determined speed and based on multiple signals received from a wireless local area network over a period of time transpiring. For example, the mobile device can determine its speed to be at or above a threshold speed and can determine that multiple signals have been received from a wireless access point over a period of time transpiring. For instance, the mobile device can determine that multiple signals, that include a same media access control address, have been received from a wireless access point over a period of time transpiring. In one or more aspects, the mobile device can utilize the wireless access point for data communications (e.g., packet data communications such as Internet protocol communications, etc.) when a determined speed of the mobile device is at or above a threshold speed and after multiple signals that include a same media access control address have been received, from the wireless access point, over a period of time transpiring.

In one or more aspects, a method includes receiving a beacon signal from a wireless access point at a mobile device. The method also includes determining, based on the beacon signal and a size of a buffer of the mobile device, a speed threshold associated with the wireless access point. The method further includes selectively transmitting data to the wireless access point based at least in part on the speed threshold.

In one or more aspects, a mobile device includes a wireless network interface and a processor. The wireless network interface is configured to communicate with a wireless access point. The processor is coupled to the wireless network interface. The processor is configured to receive a beacon signal from the wireless access point via the wireless network interface. The processor is also configured to determine, based on the beacon signal and a size of a buffer of the mobile device, a speed threshold associated with the wireless access point. The processor is further configured to selectively transmit, via the wireless network interface, data to the wireless access point based at least in part on the speed threshold.

In one or more aspects, a computer-readable storage device of a mobile device stores instructions executable by a processor to perform operations including receiving a beacon signal from a wireless access point. The operations also include determining, based on the beacon signal and a size of a buffer of the mobile device, a velocity threshold associated with the wireless access point. The operations further include selectively transmitting data to the wireless access point based at least in part on the velocity threshold.

Turning now to FIG. 1, a block diagram of one or more network communications systems and mobile devices traversing a path or route is illustrated, according to one or more aspects. As shown, one or more mobile devices (MDs) 1110-1112 can traverse a path and/or route 1510. In one or more aspects, a mobile device (MD) can traverse path and/or route 1510 via a vehicle (e.g., a boat, a motorcycle, a bus, a train, a plane, an automobile, etc.). As illustrated, MD 1110 can access a coverage 1250 of a mobile telephone network (MTN) node 1210, and MD 1112 can access a coverage 1251 of a MTN node 1211.

In another example, network 1410 can provide access to and/or services of a network 1420 and/or a network coupled to network 1420. In one or more aspects, network 1410 can be and/or implement a telecommunications network (e.g., a mobile telecommunications network).

In one or more aspects, network 1410 can be coupled to and/or include a telephony network that can include a wireless cellular telecommunications network and/or a wireless satellite telecommunications network. In one or more aspects, the telephony network can communicate information such as voice and/or data. In one or more aspects, one or more of MDs 1110-1112 can communicate with network 1410 in a wireless fashion. In one or more aspects, network 1410 provides access and/or services of one or more other networks at a lower data rate than a network 1420 can provide to one or more of MDs 1110-1112. For example, network 1410 can include less bandwidth than network 1420.

As shown, one or more wireless access points (APs) 1310-1315 can be coupled to network 1420 and can respectively provide communications access of network 1420 to one or more devices coupled to the respective wireless AP. In one or more aspects, a wireless access point (e.g., a wireless access point of wireless APs 1310-1315) can communicate with one or more devices (e.g., one or more of MDs 1110-1112) using one or more of Institute of Electrical and Electronics Engineers (IEEE) 802.16, IEEE 802.11, IEEE 802.15, IEEE 802.15.4, Z-Wave, ZigBee, wireless Ethernet, ultra wide band, wireless universal serial bus (USB) and infrared communication technologies, among others. In one or more aspects, a wireless access point (AP) can include a transceiver to communicate with one or more devices using one or more wireless methods, processes, protocols, systems, and/or wireless spectrums (e.g., frequency ranges). In one example, a wireless AP can communicate with one or more devices using one or more ISM (industrial, scientific and medical) bands. For instance, an ISM band can include a frequency range of 6.765-6.795 megahertz (MHz), 433.05-434.79 MHz, 902-928 MHz, 2.4-2.5 gigahertz (GHz), 5.725-5.875 GHz, or 24.0-24.25 GHz, among others.

In one or more aspects, network 1420 can provide access and/or services of one or more other networks to MDs 1110-1112 via one or more wireless APs. In one or more aspects, access to these networks can include one or more “services” these networks may provide. For example, these one or more services can include one or more of: email, world wide web, file transfer, printing, file sharing, file system sharing, remote file system, network file system (NFS), news, multicast, network basic input/output system (NetBIOS), encryption, domain name service (DNS), routing, tunneling, chat such as Internet Remote Chat and/or AOL Instant Messenger, gaming, licensing, license management, digital rights management, network time, remote desktop, remote windowing, audio, database (e.g., Oracle, Microsoft SQL Server, PostgreSQL, etc.), authentication, accounting, authorization, virtual local area network (VLAN) (e.g., IEEE 802.1q), virtual private network or VPN, audio, phone, Voice Over Internet Protocol (VoIP), paging, and video, among others. In one or more aspects, the one or more service can be associated with and/or correspond to one or more protocols of one or more computer and/or software applications.

In one or more aspects, network 1410 and/or network 1420 can include a wired network, a wireless network or a combination of wired and wireless networks. Network 1410 and/or network 1420 can include and/or be coupled to various types of communications networks, such as a public switched telephone network (PSTN), an Internet, a wide area network (WAN) (e.g., a private WAN, a corporate WAN, a public WAN, etc.), a local area network (LAN). In one or more aspects, a wireless AP can be coupled to a PSTN, e.g., via: Ethernet cable and DSL; a cable (television) based network; a satellite-based system; and/or a fiber based network; among others. In one or more aspects, network 1410 and/or network 1420 can include one or more wireless networks, e.g., based on IEEE 802.11 and/or IEEE 802.16. For instance, one or more of wireless APs 1310-1315 can be coupled to network 1420 in a wireless fashion. Network 1410 and/or network 1420 can include one or more DSL (digital subscriber line) and/or cable (e.g., cable television) networks and/or infrastructures.

For example, network 1410 and/or network 1420 can include one or more of: cable moderns, cable modem termination systems (CMTSs), satellite modems, DSL modems, digital subscriber line access multiplexers (DSLAMs), broadband remote access servers (BRASs), telecommunications circuits, and/or metropolitan area networks (MANs), among others. In one or more aspects, network 1420 may form part of the Internet, or may couple to other networks, e.g., other local or wide area networks such as the Internet. In one or more aspects, a wireless AP can be a system operable to be coupled to and/or include networking equipment usable to couple the wireless AP to network 1420. In one example, wireless AP 1311 can include a wired Ethernet interface that can be coupled to a cable modem or a DSL modem that can be coupled to network 1420. In another example, wireless AP 1314 can include a FDDI (fiber distributed data interface) that can be coupled to a router and/or gateway device that can be coupled to network 1420.

In one or more aspects, each MD of MDs 1110-1112 can include and/or can be coupled to one or more transceivers that allow the MD to communicate with network 1410 and/or a wireless AP of wireless APs 1310-1315. For example, MD 1110 can include or be coupled to a first transceiver that can communicate with MTN node 1210 and/or include or be coupled to a second transceiver to communicate with wireless AP 1311. For instance, MD 1110 can include or be coupled to a first transceiver that can communicate with a cellular telephone system of or coupled to network 1410 and/or include or be coupled to a second transceiver, such as a wireless Ethernet transceiver, to communicate with wireless AP 1311.

As shown, network 1410 can include computer systems 1610-1612, and computer systems 1620-1622 can be coupled to network 1410. In one or more aspects, one or more of computer systems 1610-1612 and 1620-1622 can implement and/or perform one or more operations of network 1410 and/or a mobile telephone network. As illustrated, computer systems 1630-1632 can be coupled to network 1420. In one or more aspects, each MD of MDs 1110-1112 can communicate with one or more of computer systems 1630-1632 via network 1420.

In one example, each MD of MDs 1110-1112 can communicate with one or more of computer systems 1630-1632 via network 1420 and a wireless AP (e.g., a wireless AP of wireless APs 1310-1315) coupled to network 1420. In a second example, each MD of MDs 1110-1112 can communicate with one or more of computer systems 1630-1632 via network 1420, network 1410, and a MTN node (e.g., a MTN node of MTN nodes 1210-1212) coupled to network 1410 which is coupled to network 1420. In one or more aspects, one or more of MDs 1110-1112 can communicate with one or more of computer systems 1630-1632 via one or more of an Internet protocol (IP), a transmission control protocol (TCP), a user datagram protocol (UDP), an Internet control message protocol (ICMP), a simple network management protocol (SNMP), and a hypertext transfer protocol (HTTP), among others.

In one or more aspects, a MD can determine that communications with a wireless AP are possible; however, a speed of the MD can cause a use of the wireless AP to be too brief for a significant utilization of network access or to be not possible. For instance, MD 1110 can travel at a speed and intersect a coverage 1351 of wireless AP 1311. MD 1110 can determine that communications with wireless AP 1311 are possible; however, the speed of MD 1110 can cause a use of wireless AP 1311 to be too brief for a significant utilization of network 1420 or to be not possible.

In one or more aspects, a coverage of a wireless AP or a MTN node can include an area or a volume. For example, coverage 1351 can include an area with a radius of one hundred and thirty-two (132) feet from an antenna of wireless AP 1311, and the speed of MD 1110 can be sixty (60) miles per hour (MPH). For instance, AP 1311 can be at fixed location or can have a zero (0) speed. Accordingly, sixty (60) MPH yields eighty-eight (88) feet per second (FPS). In this example, a utilization of wireless AP 1311 to access network 1420 can be possible for three (3) seconds. This amount of time can be too brief for a significant utilization of network 1420 or utilization of network 1420 may not be possible within this amount of time. Furthermore, this amount of time can reduce a quality of service if MD 1110 communicates with wireless AP 1311. In one or more aspects, a speed of a MD can be determined, and the MD may not communicate with a wireless AP (e.g., a wireless AP of wireless APs 1310-1315) when the determined speed of the MD is at or above a specific speed.

For example, the specific speed for MD 1110 can be eighteen (18) MPH, and MD 1110 may not communicate with wireless AP 1310 when the speed of MD 1110 is determined to be at or above eighteen (18) MPH. When MD 1110 is traveling below eighteen (18) MPH, MD 1110 can utilize wireless AP 1311 for a period of time up to ten (10) seconds, in this example. When MD 1110 is traveling at or above eighteen (18) MPH, MD 1110 can utilize MTN node 1210 to communicate with network 1420, in this example. For instance, MD 1110 can utilize MTN nodes 1210-1212 when intersecting respective coverages 1250-1252 and at a speed of or above eighteen (18) MPH to communicate with network 1420, and MD 1110 can utilize wireless APs 1310-1315 when intersecting respective coverages 1350-1355 and below a speed of eighteen (18) MPH to communicate with network 1420.

In one or more aspects, a speed of a MD can be determined and a size of a buffer, that can be transmitted, can be determined, and the MD can communicate with a wireless AP (e.g., a wireless AP of wireless APs 1310-1315) when the determined speed of the MD is at or below a specific speed and when the determined size of the buffer is at or below a specific size. For example, transmitting the buffer to a wireless AP can utilize an amount of time up to ten (10) seconds, based on the determined size of the buffer and based on a communication speed with the wireless AP. For instance, if the MD can communicate with the wireless AP for at least ten (10) seconds, based on the determined speed of the MD, then the MD can transmit contents of the buffer to the wireless AP.

Turning now to FIG. 2, a block diagram of one or more network communications systems and at least one mobile device and a wireless access point traversing a path or route is illustrated, according to one or more aspects. As shown, a vehicle 2110 can be traversing path or route 1510.

As illustrated, vehicle 2110 can include a wireless AP 2310, and one or more of MDs 1110-1112 can wirelessly communicate with wireless AP 2310 when intersecting a coverage 2350 of wireless AP 2310. For example, one or more of MDs 1110-1112 can be traveling at relatively the same speed as AP 2310 and can utilize one or more variations of one or more signals from AP 2310 in determining that AP 2310 can be utilized for communications with one or more of computer systems 1630-1633.

In one or more aspects, wireless AP 2310 can include a first wireless network interface that can communicate with one or more MDs (e.g., one or more of MDs 1110-1112), and wireless AP 2310 can include a second wireless network interface that can communicate with one or more MTN nodes (e.g., one or more of MTN nodes 1210-1212). As illustrated, wireless AP 2310 can intersect coverage 1250 of MTN node 1210. When wireless AP 2310 intersects a coverage of a MTN node, wireless AP 2310 can utilize its second wireless network interface to communicate with the MTN node. In one or more aspects, wireless AP 2310 can include one or more structures and/or perform one or more functions of a router that can allow one or more MDs to communicate with a MTN node via the first and second wireless network interfaces of wireless AP 2310. For example, one or more of MDs 1110-1112 can utilize wireless AP 2310 to communicate with one or more computer systems coupled to network 1420.

In one or more aspects, wireless AP 2310 can transmit a signal, via the first wireless network interface, indicating that wireless AP 2310 can be utilized by one or more MDs at or above a specific speed for a MD. In one example, the signal can indicate that wireless AP 2310 can be utilized at any speed. In second example, the signal can include speed information that can be utilized by a MD in determining if network communications via wireless AP 2310 are possible. For instance, the signal can include a speed of wireless AP 2310 that can be utilized by a MD in determining if network communications via wireless AP 2310 are possible. In another example, the signal can include direction information that can be utilized by a MD in determining if network communication via wireless AP 2310 is possible.

In one or more aspects, the signal can be included in an IEEE 802.11 beacon. In one example, the IEEE 802.11 beacon can include a service set identifier (SSID). In a second example, the IEEE 802.11 beacon can include a beacon frame. In one instance, the beacon frame can include capability information that can include speed information, associated with wireless AP 2310, that can be utilized by a MD in determining if network communications via wireless AP 2310 are possible. In another instance, the beacon frame can include information that can indicate that wireless AP 2310 can be utilized at any speed.

For example, the one or more transmitters, the one or more receivers, and/or the one or more transceivers of the BTS can communicate via a layer one of an air interface (e.g., a wireless interface). In one or more aspects, the one or more antennas of the BTS can be mounted on a roof of a building, on a mast, on a tower (e.g., a cellular telephone communications tower), and/or on a side of a structure (e.g., a building, a parking garage, a lamp post, etc.).

At 8020, a wireless AP can transmit, via a first wireless network interface, a signal that includes information associated with the speed of the wireless AP.

In one or more aspects, method elements 8030-8060 can be performed with reference to method elements 7020-7050 (of FIG. 7), respectively.

Turning now to FIG. 9, a method of determining speed information associated with a mobile device is illustrated, according to one or more aspects. At 9010, a first position of a MD (e.g., a MD of MDs 1110-1112) can be determined. For example, one or more computer systems (e.g., one or more of computer systems 1610-1622) can determine the position of MD 1110. In one or more aspects, the position of the MD can be associated with position information (e.g., latitude, longitude, altitude, etc.), and the one or more computer systems can determine the position information associated with the position of the MD.

In one example, position information can be determined using a triangulation system, method, and/or process. In one instance, at least three antennas of at least three respective base transceiver stations included in or coupled to network 1410 can receive one or more signals from the MD, and strength of the one or more signals and/or timing the signal propagation from the MD to the at least three antennas of at least three respective base transceiver stations can be used in determining the position information. In another instance, at least two directional antennas of at least two respective base transceiver stations included in or coupled to network 1410 can receive one or more signals from the MD, and strength of the one or more signals and/or timing the signal propagation from the MD to the at least two antennas of at least two respective base transceiver stations can be used in determining the position information.

In one or more aspects, strength of a signal from the MD to an antenna of a base transceiver station (e.g., a MTN node) included in or coupled to network 1410 can be utilized in determining the position information. For example, a first strength of a signal transmitted from the MD can be different from a second strength of the signal received by the antenna, and a distance from the antenna can be determined based on a difference in transmitted strength of the signal and received strength of the signal. For instance, one or more computer systems 1610-1622 can communicate a signal to the MD, where the signal includes information that indicates the first signal strength, and the MD can transmit one or more signals, at or close to the first signal strength, to network 1410. Network 1410 can receive, at the second signal strength, the one or more signals transmitted by the MD, where the second signal strength is less than the first signal strength due to path loss, terrain, etc.

Since the first signal strength can depend on free space path loss, air path loss, terrain path loss (e.g., hills, valleys, mountains, vegetation, etc.), and/or structure path loss (e.g., buildings, bridges, towers, etc.), among others, a data structure that includes information associated with these dependencies can be utilized in determining a path loss attenuation factor and/or the position based on signal strength, according to one or more aspects. In one example, a received first signal strength from MD 1110 at a first position and a second received signal strength from MD 1111 at a second, different, position can be the same or similar while distances of the first and second positions to respective first and second antennas of a base transceiver station can be different. For instance, a distance from the second position to the second antenna of the base transceiver station can be greater than a distance from the first position to the first antenna of the base transceiver station, and the second received signal strength from MD 1111 can be affected by air path loss while the first received signal strength from MD 1110 can be affected by structure path loss.

In one or more aspects, utilizing sector information associated with the first and second antennas and the data structure that includes information associated with one or more of free space path loss, air path loss, terrain path loss, and structure path loss can be used and/or aid in determining the differences in the distances by gauging the first and second received signal strengths with path loss information of the data structure. In one or more aspects, a vicinity of the antenna, that can communicate with a MD, can include a sector of an area or volume covered by the antenna, and the sector can be used in determining the position information. In one or more aspects, determining the distance from the antenna can be used in determining the position information and/or can be based on determining a path loss attenuation factor. For example, path loss attenuation factor can be based on one or more of free space path loss, air path loss, terrain path loss, and structure path loss.

At 9020, an amount of time transpired can be determined. For example, a computer system of computer systems 1610-1622 can determine that an amount of time has transpired. At 9030, a second position of the MD can be determined. For example, one or more computer systems (e.g., one or more of computer systems 1610-1622) can determine the position of MD 1110. In one or more aspects, the second position of the MD can be determined similarly to or the same as the first position determined at 9010.

At 9040, a speed of the MD can be determined. For example, a computer system of computer systems 1610-1622 can calculate a speed of MD 1110 by calculating a distance between the first position and the second position that has been traversed within the amount of time that has transpired. In one or more aspects, a computer system of computer systems 1610-1622 can calculate a velocity (e.g., a speed and direction) of a MD by calculating a distance between the first position and the second position that has been traversed within the amount of time that has transpired. At 9050, the speed of the MD can be provided to the MD. For example, MTN node 1210 can transmit the speed of MD 1110 to MD 1110. In one or more aspects, a speed of a wireless AP can be determined using the method described with reference to FIG. 9. For example, “a MD” and “MD 1110” can be substituted by “a wireless AP” and “wireless AP 2310”, respectively.

Turning now to FIG. 10, a method of operating a mobile device is illustrated, according to one or more aspects. At 10010, speed information associated with a MD can be determined. In one example, MD 1110 can determine its speed. For instance, MD 1110 can determine its speed utilizing position device 5080. In another example, MD 1110 can determine its speed by receiving its speed via network 1410 and/or MTN node 1210. At 10020, one or more signals can be received from a wireless AP. For example, MD 1110 can receive one or more signals from wireless AP 2310. At 10030, it can be determined if network communications via the wireless AP are possible.

In one example, determining if network communications via the wireless AP are possible can include determining an amount of time that the wireless AP can be utilized. In one instance, determining if network communications via the wireless AP are possible can include determining if the amount of time for utilizing the wireless AP is too brief (e.g., three seconds). In another instance, determining if network communications via the wireless AP are possible can include determining if the amount of time for utilizing the wireless AP would reduce a quality of service if the MD communicates with the wireless AP. For example, if the amount of time for utilizing the wireless AP would not reduce a quality of service, then network communications utilizing the wireless AP can be considered optimal, and it can be determined that network communications via the wireless AP are possible, since communications utilizing the wireless AP can be considered optimal.

If network communications via the wireless AP are possible, first data that includes a request can be transmitted to the wireless AP, at 10040. For example, MD 1110 can transmit, via network interface 5031, first data that includes a request to wireless AP 2310. In one or more aspects, the first data can include address information that can be utilized in routing the request and/or the first data to a computer system (e.g., a computer system of computer systems 1630-1632) coupled to a network (e.g., network 1420).

For example, the first data can include one or more IP packets that include a destination address (e.g., an IP address) of a computer system coupled to a network. In one or more aspects, the request included in the first data can include a request for information and/or a request to store and/or transmit information. In one example, the request included in the first data can include a request for a web page from computer system 1630. In second example, the request included in the first data can include a request for email addressed to an email address (e.g., accessible via computer system 1631). In third example, the request included in the first data can include a request to send an email message to a first email address from a second email address. In another example, the request included in the first data can include a request to upload data. For instance, the request can include one or more of a file and data to be inserted into a database.

At 10050, second data can be received from the wireless AP. For example, MD 1110 can receive, via network interface 5031, second data from wireless AP 2310. For instance, the second data can include a response to the request included in the first data. In one example, the response included in the second data can include a web page from computer system 1630. In second example, the response included in the second data can include one or more email messages addressed to an email address (e.g., accessible via computer system 1631). In third example, the response included in the second data can include a confirmation and/or acknowledgement indicating that an email message has been sent or will be sent to a first email address from a second email address. In fourth example, the response included in the second data a confirmation and/or acknowledgement indicating that data has been successfully uploaded. In another example, the response included in the second data an error and/or a negative acknowledgement (NAK) indicating that data has not been successfully uploaded.

If network communications via the wireless AP are not possible, first data that includes a request can be transmitted to a MTN node, at 10060. For example, MD 1110 can transmit, via network interface 5030, first data that includes a request to MTN node 1210. At 10070, second data from the MTN node can be received. For example, MD 1110 can receive, via network interface 5030, second data from MTN 1210. For instance, the second data can include a response to the request included in the first data.

Turning now to FIG. 11, a method of determining if network communications via a wireless access point are possible is illustrated, according to one or more aspects. At 11010, it can be determined if the one or more signals received from the wireless AP include two or more signals that include identification information and have been received over a period of time transpiring. In one or more aspects, the identification information can include one or more of a media access control (MAC) address, a SSID, and a basic service set identifier (BSSID), among others. If the one or more signals received from the wireless AP do not include two or more signals that include identification information or have not been received over the period of time transpiring, it can be determined that network communications via the wireless access point are not possible, at 11040.

If the one or more signals received from the wireless AP include two or more signals that include identification information and have been received over the period of time transpiring, it can be determined if the identification information has been repeatedly received over the period of time transpiring, at 11020. In one example, MD 1110 can receive a same MAC address, a same SSID, and/or a same BSSID over the period of time transpiring. If the identification information has been repeatedly received over the period of time transpiring, it can be determined that network communications via the wireless AP are possible, at 11030. If the identification information has not been repeatedly received over the period of time transpiring, it can be determined that network communications via the wireless access point are not possible, at 11040.

Turning now to FIG. 12, a method of determining if network communications via a wireless access point are possible is illustrated, according to one or more aspects. At 12010, it can be determined if the one or more signals received from the wireless AP include information indicating that the wireless AP can be used at any speed. If the one or more signals received from the wireless AP include information indicating that the wireless AP can be used at any speed, it can be determined that network communications via the wireless access point are possible, at 12020. If the one or more signals received from the wireless AP do not include information indicating that the wireless AP can be used at any speed, it can be determined that network communications via the wireless access point are not possible, at 12030.

Turning now to FIG. 13, a method of determining if network communications via a wireless access point are possible is illustrated, according to one or more aspects. At 13010, it can be determined if the one or more signals received from the wireless AP include information indicating a speed of the wireless AP. If the one or more signals received from the wireless AP do not include information indicating a speed of the wireless AP, it can be determined that network communications via the wireless access point are not possible, at 13020. If the one or more signals received from the wireless AP include information indicating a speed of the wireless AP, it can be determined if the speed of the wireless AP and the speed of the MD are within a threshold, at 13030.

In one or more aspects, the threshold can indicate a range of relative speeds of a MD to a wireless AP or of a wireless AP to a MD. In one example, it can be determined if the speed of the wireless AP is within plus or minus a threshold of the speed of the MD. In a second example, it can be determined if |Speed_(AP)−Speed_(MD)|≤Threshold or if |Speed_(AP)−Speed_(MD)|<Threshold (e.g., Threshold=18 MPH). For instance, |Speed_(AP)−Speed_(MD)| can be calculated by calculating √{square root over ((Speed_(AP)−Speed_(MD))²)}. If the speed of the wireless AP and the speed of the MD are within the threshold, it can be determined that network communications via the wireless AP are possible, at 13040. If the speed of the wireless AP and the speed of the MD are not within the threshold, it can be determined that network communications via the wireless AP are not possible, at 13020.

Turning now to FIG. 14, a method of determining if network communications via a wireless access point are possible is illustrated, according to one or more aspects. At 14010, it can be determined if the one or more signals received from the wireless AP include information indicating a velocity (e.g., a speed and a direction or

_(AP)) of the wireless AP. If the one or more signals received from the wireless AP do not include information indicating a velocity of the wireless AP, it can be determined that network communications via the wireless access point are not possible, at 14020. If the one or more signals received from the wireless AP include information indicating a velocity (e.g., a speed and a direction or

_(MD)) of the wireless AP, it can be determined if the velocity of the wireless AP and a velocity of the MD are within a threshold, at 14030.

In one or more aspects, the threshold can indicate a range of relative speeds and directions of a MD to a wireless AP or of a wireless AP to a MD. For example, a relative speed and direction of the wireless AP to the MD can be calculated via

 V AP ⁢ ⁢ V MD  V MD  -  V MD   . In one instance, if

 V AP ⁢ ⁢ V MD  V MD  -  V MD   ≤ Threshold (e.g., 18 MPH), it can be determined that network communications via the wireless AP are possible, at 14040. If

 V AP ⁢ ⁢ V MD  V MD  -  V MD   > Threshold , it can be determined that network communications via the wireless AP are not possible, at 14020. In another instance, if

 V AP ⁢ ⁢ V MD  V MD  -  V MD   < Threshold , it can be determined that network communications via the wireless AP are possible, at 14040. If

 V AP ⁢ ⁢ V MD  V MD  -  V MD   ≥ Threshold , it can be determined that network communications via the wireless AP are not possible, at 14020.
